Trachypithecus
''Trachypithecus'' (derived from Greek , meaning "rough" and , meaning "monkey") is a genus of Old World monkeys containing species known as lutungs, langurs, or leaf monkeys. Their range is much of Southeast Asia (northeast India, Vietnam, southern China, Borneo, Thailand, Java, and Bali). The name "lutung" comes from the Sundanese language meaning "blackness", ultimately from Proto-Austronesian *''luCuŋ'' (which originally referred to the Formosan rock macaque); it is preferred in one paper because the authors wanted the name langurs to only refer to monkeys in the genus '' Semnopithecus'', although some "lutungs" are now "langurs" again. Evolution Genetic analysis indicates that the ancestors of the modern species of lutung first differentiated from one another a little over 3 million years ago, during the late Pliocene. The various species alive today then diverged during the Pleistocene, presumably driven by habitat changes during the Ice Ages. The oldest fossils ...

Indochinese Lutung
Germain's langur (''Trachypithecus germaini'') is an Old World monkey native to Thailand, Myanmar, Cambodia, Laos and Vietnam. The monkey was previously included in '' Trachypithecus cristatus'' and '' Trachypithecus villosus''. Two subspecies were recognized: *''Trachypithecus germaini germaini'' *''Trachypithecus germaini caudalis'' Taxonomy and evolution Germain's langur is part of the leaf monkey subfamily Colobinae. Two subspecies of the Germain's langur are recognized: ''Trachypithecus germaini germaini'' and ''Trachypithecus germaini caudalis.'' However, the classification of the Germain's langur has been contested, with ''T. germaini'' being grouped with other species in its subfamily. ''T. germaini'' and '' T. margarita'' were considered to be a single species, ''T. villosus,'' but morphological and genetic evidence has shown that they are distinct. ''T. germaini'' has also been grouped with '' T. cristatus'' until recent reclassifications. ''Trachypithecus germaini'' ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Dusky Leaf Monkey
The dusky leaf monkey (''Trachypithecus obscurus''), also known as the spectacled langur or the spectacled leaf monkey, is a species of primate in the family Cercopithecidae. It is found in Peninsular Malaysia, Myanmar and Thailand, and can occasionally be found in Singapore. During the day, these small, Folivore, folivorous primates divide in sub-groups and forage for vegetation and fruit throughout the tropical forests. According to the International Union for Conservation of Nature, IUCN, the dusky leaf monkey's population is declining due to habitat loss, poaching, and anthropogenic land use, which prompted the IUCN to classify the species as Endangered species, endangered in 2015. Taxonomy Within the Cercopithecidae family, the dusky leaf monkey is a member of the genus ''Trachypithecus''. Although most researchers agree with this classification, others believe that this primate should be categorized under the genus ''Presbytis.'' Subspecies Researchers have also dispute ...
